This tunnel is shaped colorful caterpillar; is gay, it corresponds to the world of children. It is easy to open: one has only to detach the scratches. Easy to store too: they put up, is pressed and placed scratches. When folded, it takes up little space, outside its course diameter (I bought a tunnel in a famous Swedish store: Swedish tunnel remains bulkier when folded) The fact that this tunnel is closed really liked my kids enjoyed the cocoon appearance (always compare with the Swedish tunnel: it does not have these doors) Be careful with possible falls when crossing energetic because the tunnel rolls. The children play well with if I included in a motor course. Only put like that, they get tired quickly.
